Class LargeMessageControllerImpl

java.lang.Object
org.apache.activemq.artemis.core.client.impl.LargeMessageControllerImpl
All Implemented Interfaces:
DataInput, ActiveMQBuffer, LargeMessageController
public class LargeMessageControllerImpl extends Object implements LargeMessageController
This class aggregates several SessionReceiveContinuationMessage as it was being handled by a single buffer. This buffer can be consumed as messages are arriving, and it will hold the packets until they are read using the ChannelBuffer interface, or the setOutputStream or saveStream are called.

    • setIndex

      public void setIndex(int readerIndex, int writerIndex)
      Description copied from interface: ActiveMQBuffer
      Sets the readerIndex and writerIndex of this buffer in one shot. This method is useful when you have to worry about the invocation order of ActiveMQBuffer.readerIndex(int) and ActiveMQBuffer.writerIndex(int) methods. For example, the following code will fail: 
       // Create a buffer whose readerIndex, writerIndex and capacity are
 // 0, 0 and 8 respectively.
 ChannelBuffer buf = ChannelBuffers.buffer(8);

 // IndexOutOfBoundsException is thrown because the specified
 // readerIndex (2) cannot be greater than the current writerIndex (0).
 buf.readerIndex(2);
 buf.writerIndex(4);

      The following code will also fail: 

       // Create a buffer whose readerIndex, writerIndex and capacity are
 // 0, 8 and 8 respectively.
 ChannelBuffer buf = ChannelBuffers.wrappedBuffer(new byte[8]);

 // readerIndex becomes 8.
 buf.readLong();

 // IndexOutOfBoundsException is thrown because the specified
 // writerIndex (4) cannot be less than the current readerIndex (8).
 buf.writerIndex(4);
 buf.readerIndex(2);

      By contrast, ActiveMQBuffer.setIndex(int, int) guarantees that it never throws an IndexOutOfBoundsException as long as the specified indexes meet basic constraints, regardless what the current index values of the buffer are: 

       // No matter what the current state of the buffer is, the following
 // call always succeeds as long as the capacity of the buffer is not
 // less than 4.
 buf.setIndex(2, 4);
      Specified by:
      setIndex in interface ActiveMQBuffer
      Parameters:
      readerIndex - The reader's index
      writerIndex - The writer's index
